INSTALLATION & MAINTENANCE INSTRUCTIONS

Models QBR and USBR (including QBRH hurricane option)

For the QBR Model with hurricane construction that complies with Florida Building Code including High Velocity Hurricane Zones (HVHZ) see the ADDITIONAL INSTALLATION AND MAINTENANCE INSTRUCTIONS on page 4.

RECEIVING AND INSPECTION

Immediately upon receipt of a shipment, carefully inspect for damage and shortage. Turn the impeller by hand to see that it turns freely and does not bind. If any damage and/or shortage is detected or suspected, the carrier must be asked to conduct an inspection. The consignees representative should not accept a shipment without a notation on the delivery receipt indicating items not delivered or the apparent extent of damage.

When a shipment is opened and damage is found which was not evident externally (concealed damage), it is mandatory that the consignee request an immediate inspection by the carrier. Report any damage to the carrier within 15 days. Failure to report damage within the above time limit will result in rejection of a claim.

HANDLING

When handling fans and their accessories, always use equipment and methods that will not cause damage. Fans should be lifted using slings and padding or spreaders to avoid damage.

CAUTION! Always make sure that all lifting and handling equipment and techniques conform to current safety standards.

Avoid lifting fans in a way that will bend or distort fan parts.

Never pass slings or timbers through the orices of fan.

CAUTION! Do not lift by the fan hood. Fans with special coatings or paints must be protected in handling to prevent damage.

STORAGE

several points and maintain the atmosphere at 40% relative humidity, or lower.

It may be necessary to use trays of renewable desiccant or

portable dehumidier to remove moisture from the air in the

storage enclosure.

Thermostatically controlled portable heaters (vented to outdoors) may be required to maintain even temperatures inside the enclosure.

CAUTION! Provide re extinguishers, or re alarms, or

emergency response communication to protect building and

equipment against re damage. Be sure that building and storage practices meet all local, state and federal re and

safety codes.

The following fans or accessories must be stored indoors, in a clean dry atmosphere:

a. Propeller wall fans not in wall housings. b. Any fan protected by a cardboard carton. c. Motors dismounted from fans. d. Spare wheels or propellers. e Belts, sheaves, bushings and other parts when not

mounted on fan.

f. Boxes, bags or cartons of hardware. g. Curbs h. Dampers

Remove any accumulations of dirt, water, ice or snow and wipe dry before moving indoor storage. Allow cold parts to reach room temperature to avoid sweating of metal parts. Open boxes or cartons. Remove any accumulated moisture; if necessary use portable electric heaters to dry parts and packages. Leave coverings loose to permit air circulation and to permit periodic inspection.

Rotate wheels or propellers by hand to distribute bearing grease over the entire bearing surfaces.

Fans are protected against damage during shipment. If they cannot be installed and put into operation immediately upon receipt certain precautions are necessary to prevent deterioration during storage. Responsibility for integrity of fans and accessories during storage must be assumed by the user. The manufacturer will not be responsible for damage during storage. These suggestions are provided solely as a convenience to the user, who shall make his own decision as to whether to use any or all of them.

INDOOR: The ideal storage environment for fans and accessories is indoors, above grade, in a low humidity atmosphere which is sealed to prevent the entry of blowing dust, rain, or snow. Temperatures should be evenly maintained at between 70°F and 105°F (wide temperature swings may cause condensation and “sweating” of metal parts). Windows should be covered to prevent temperature variations caused by sunlight. Provide thermometers and humidity indicators at

Store at least 3 1⁄2” off the oor on wooden blocks covered with moisture proof paper or polyethylene sheathing. Provide aisles between parts and along all walls, to permit air circulation and space for inspection.

OUTDOOR: Fans designed for outdoor use may be stored outdoors, if absolutely necessary. The storage area should be reasonably level and drained or ditched to prevent accumulation of water. Fencing and lighting for security are desirable. Roads or aisles for portable cranes and hauling equipment are needed. Consider the use of drift fencing to minimize accumulation of blowing snow or dirt.

The following fans may be stored outdoors, if dry indoor storage space is not available:

a. Fans intended for outdoor use that are crated in wood. b. Wall fans installed in wall housings.

All fans must be supported on wooden blocks or timbers above water or normal snow levels. Provide enough blocking to prevent settling into soft ground. Fans should be set in place using the directional arrow markings on the crate as a guide.

Locate pieces far enough apart to permit air circulation, sunlight, and space for periodic inspection. Place all parts on their supports so that rain water will run off, or to minimize water accumulation. Do not cover parts with plastic lm or tarps-these cause condensation of moisture from the air passing through heating and cooling cycles.

Fan wheels and propellers should be blocked to prevent spinning caused by strong winds.

INSPECTION AND MAINTENANCE

DURING STORAGE

Inspect fans and accessories at least once per month, while in storage. Log results of inspection and maintenance performed. A typical log entry should include the following:

a. Date b. Inspectors Name c. Name of Fan d. Location e. Condition of Paint or Coating f. Is moisture present? g. Is dirt accumulated? h. Corrective steps taken?

If moisture or dirt accumulations are found on parts, the source should be located and eliminated. Fans should be

rotated at each inspection by hand ten to fteen revolutions to

redistribute the motor and bearing lubricant.

If paint deterioration begins, consideration should be given to touch-up or repainting. Fans with special coatings may require special techniques for touch-up or repair.

Machined parts coated with rust preventive should be restored to good condition promptly if signs of rust occur. The most critical items are pulleys, shafts and bearing locking collars.

At the rst sign of rusting on any of the above parts, remove

the original rust preventive coating with petroleum solvent and clean lint-free cloths. Polish any remaining rust from surfaces

with crocus cloth or ne emery paper and oil. Do not destroy

the continuity of the surfaces. Wipe clean with lint-free cloths and recoat surfaces evenly and thoroughly with Tectly 506 (Ashland Oil Company) or equal. For hard to reach internal surfaces or for occasional use, consider using Tectly 511M Rust Preventive or WD40 or equal.

REMOVING FROM STORAGE

As fans are removed from storage to be installed in their nal

location, they should be protected and maintained in similar fashion, until the fan equipment goes into operation.

INSTALLATION

1. CAUTION! This unit has rotating parts and safety precautions should be exercised during installation, operation and maintenance.

2. WARNING! Do not use in hazardous environments where fans electrical system could provide ignition to

combustible or ammable materials, unless the unit is specically built for hazardous environments.

3. WARNING! If gases, other than clean air, are to be exhausted using the fan, then the user bears the responsibility of determining that the fan is appropriate and safe for the application.

4. The fan should be mounted on a solid foundation equipped with anchoring devices (such as anchor bolts). Level the fan on the foundation, shimming where necessary. Anchor the fan securely to the foundation. If vibration isolators are used, these should be installed between the fan and the foundation. When mounted on suspended platforms adequate cross bracing will be required.

5. Check pulley alignment and belt tension. Belt should

deect 1/2” to 3/4” (13mm to 19mm) when depressed by

hand midpoint between pulleys.

6. CAUTION! Before proceeding, make sure electrical service to fan is locked in “OFF” position.

7. All wiring should be in accordance with local ordinances and the National Electric Code.

8. WARNING! Check voltage at the fan to see if it corresponds with the motor nameplate. High or low voltage can seriously damage the motor. Extra care should be taken when wiring two speed motors since improper connections will damage motor and void motor warranty.

9. Apply power momentarily and compare the rotation of the impeller with directional arrow on fan. In the case of three phase motors, the direction can be reversed by interchanging any two of the three motor leads. In the case of single phase motors, the reversing instructions appear on the wiring diagram in the motor wiring compartment.

10. WARNING! Operation in the wrong direction will deliver air but will overload the motor and could seriously damage the motor.

11. OUTDOORS When installed outdoors, units should be provided with Weather Covers available as an optional accessory from the Company. Outlet dampers attached to the fan discharge should be normally closed when the fan is not running.

12. CAUTION! Inlet guards (available from the company as optional equipment) must be installed whenever the fan is installed without ducts attached to the fan inlet.

13. CAUTION! Guards must be installed when fan is within reach of personnel or within eight (8) feet (2.5m) of working level or when deemed advisable for safety.

14. IMPELLER - INLET VENTURI ADJUSTMENT

Adjustment can be achieved through the use of the slotted

holes provided in the fan construction.

For vertical movement, adjust the bearing base support

up or down on the side plates of the motor and drive compartment. After any adjustment, the bearing base should be checked to assure its being level.

For horizontal movement the lower half of the duplex split

pillow bearing housing is slotted for sideways adjustment. By loosening either set of these bolts, the impeller can be moved to provide running clearance between it and the inlet venturi. Be sure to re-tighten all bolts after proper clearances are obtained.

MAINTENANCE

1. Under normal usage, no spare parts are recommended for one year of operation. Recommended spare parts are shown on page 5.

2. CAUTION! Before proceeding, make sure the electrical service to the fan is locked in “OFF” position.

WINDMILLING: Even when the power supply is locked

out, fans may cause injury or damage if the impeller is subject “windmilling” which is the turning of the impeller and drive components due to a draft in the system. To guard against this hazard, the impeller should be secured to physically restrict rotational movement.

3. REGULAR MAINTENANCE Determined by the condition of the air passing through the fans, regularly scheduled inspection of all fan parts establishes a good maintenance routine. When the air is clean, maintenance can be as infrequent as once a year. When air is contaminated, maintenance may be required as often as once a month. Regular maintenance should include inspection and cleaning of all fan parts.

4. Check belt tension after rst 48 hours of operation and

thereafter annually. Belt should depress its width when

pressed rmly inward at midway point between the pulleys.

Too much tension will damage bearings. Belt should be tight enough to prevent slippage. When replacing worn belt, replace motor pulley if “shoulder” is worn in groove. For 2 belt drives, be sure to replace both belts with a matched set. Do not adjust belts too tightly as this will cause undue wear on the bearings of both fan and motor. Motor pulleys should be inspected regularly and replaced if they show evidence of excessive wear or “grooving”.

WARNING! Do not operate at speeds higher than that

cataloged for this equipment. Do not replace motor pulley with a larger diameter pulley. Do not replace the fan pulley with one smaller in diameter. The pulley ratios are set so that the motor will not be overloaded.

5. Impeller shaft bearings on units with duplex split pillow block housing are prelubricated and do not require relubrication. Units with pillow block bearings have

grease ttings and, under normal operation will need no

relubrication for 3 to 5 years. If relubrication is required, use a grease conforming to NLGI No. 2. CAUTION! Lubricating bearings with a high pressure gun can blow

bearing seals and overll the bearing with grease. This

condition can result in excessive churning and over heating. For normal operating conditions it is standard

practice to ll only 30% of the bearing void with grease.

Do not over lubricate.

NOTE: If locking collar type bearing is used, collar must

rst be positioned against inner race on bearing nearest

impeller and turned in direction of impeller rotation with drift pin and hammer until it locks. Locking collars must be on inboard (facing) sides of the bearings. Secure bearing to shaft with set screw. Lock and secure other bearing to shaft in same manner.

NOTE: If pillow block type bearings are used, slide

bearings onto the shaft to desired location and bolt bearing block securely to support base. Slide shaft back and forth in secured bearing (do not drive with hammer) and rotate to make certain it turns freely. Check correct position of

impeller with inlet orice. Then secure bearings to shaft

by tightening set screws.

6. Motor bearings are prelubricated. Consult information printed on the motor for lubrication instructions.

SET SCREW TIGHTENING SCHEDULE

1. Before initial operation of the fan, tighten set screws according to the procedure outlined below.

2. After 500 operating hours or three months, whichever

comes rst, tighten set screws to the full recommended

VARIABLE FREQUENCY DRIVES AND MOTORS

There are occasions when a Variable Frequency Drive (VFD) will cause poor motor performance and possible damage. To avoid these problems, the Company recommends the following:

1. Select compatible motor and VFD inverter; if possible, the motor and the inverter should be from the same manufacturer or at least the inverter selected should be recommended by the motor manufacturer.

2. A motor shaft grounding system should be used to prevent motor bearing damage from eddy currents.

NOTE: The Company will not honor motor warranty

claims if the customer fails to follow these recommendations.
